Teenager spent four months in hospital

Sam had been using a rubber ring to float in the school pool at the time but slipped under water for about 90 seconds.

He suffered a cardiac arrest and spent more than four months in hospital.

The defendants were originally charged with wilful neglect of a person without mental capacity, which they denied at an earlier hearing.

However, today when the trial was due to commence, the two women pleaded guilty to an alternative count of failing to take reasonable care for the health and safety of Sam Sebastian, a person who may have been affected by their acts and omissions at work.
